The Harvard Museum of Natural History (26)

The Harvard Museum of Natural History on the Harvard University campus has a very extensive collection of minerals, which are helpfully organized by chemical composition: All the native elements first, then all the sulfides, and so on. They also have the most amazing collection of realistic glass flowers. The samples listed under this category are of course not physically in the table: They are located in the museum and I'm just including pictures of them because I think they are interesting.
